Abstract

The utility model discloses a vibrating screening device, which comprises a grating plate (3) arranged above a material receiving trough (7). 2) It is fixed on the edge of the top plane of the receiving trough, and the lower side grate is fixed on the edge of the top plane on the other side of the receiving trough through the connecting rod (4) and the spring (2). The grate plate in this device is installed obliquely. When the grate plate vibrates, the separated bulk materials can fall into the bulk chute on the side of the tank through the bulk material discharge port along the slope, and then enter the crusher or be discharged to a temporary pile. The material level is waiting for the car to transport away, which reduces the workload of manual picking and improves efficiency.

Description

A vibrating screening device

technical field

The utility model relates to a screening device for lumpy, spherical or flake bulk materials.

Background technique

Metallurgy, coal, mining, cement and other industries have a large amount of bulk materials. If there is no conventional vibrating screen for screening, a simple screening process is required to remove impurities and large pieces to meet the process requirements. Usually, a vibrating screening device is used. Get this done. In the existing vibrating screening device technology, the vibrating screening device mainly includes a vibrating motor, a spring, and a grate. The grate is installed horizontally on the surface of the receiving trough, and large materials and impurities are manually removed. When the bulk rate of raw materials is high, the workload of manual picking is large, and there will be a phenomenon that the slot surface is blocked due to untimely picking of bulk.

Utility model content

The purpose of the utility model is to provide a vibration screening device for sorting bulk raw materials.

In order to achieve the above purpose, the following technical solution is adopted: a vibrating screening device, including a grating plate arranged above the material receiving trough, characterized in that: the grating plate is arranged obliquely, and the higher side grate plate connected with a vibration motor passes through The spring is fixed on the edge of the top plane of the material receiving trough, and the lower side grating plate is fixed on the other side of the material receiving trough top plane edge through the connecting rod 4 by the spring.

In order to facilitate the automatic output of bulk raw materials, a corresponding bulk raw material outlet is provided on the wall of the receiving chute of the low-side grate plate.

The connecting rod 4 is composed of a first connecting rod fixed on the grating plate and a second connecting rod hinged on the top plane edge of the receiving trough.

The beneficial effects of the utility model are: the grating plate in the device is installed obliquely, when the vibrating motor is working, the separated bulk material can fall into the bulk chute on the side of the tank through the bulk raw material outlet along the slope, and enter The crusher may be discharged to the temporary stacking position, waiting for the car to be transported away, which reduces the workload of manual picking and improves efficiency.

Description of drawings

FIG. 2 is a top view of FIG. 1 .

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figures 1 and 2, a vibration screening device includes a grate 3 connected to a vibration motor 1, and the grate 3 is a grid plate with a beam in the middle. A row of springs 2 are arranged on one side bottom of the vibrating motor 1 place grating plate, which is fixed on the fixed concrete or steel structure groove on the top plane of the feeding trough 7 . The other side of the grating plate 3 is installed on the edge of the other side of the top plane of the material receiving chute 7 through a hinge.

Grate plate 3 forms a kind of flexible connection structure by spring 2 and the fixed concrete or steel structure groove on the top side wall of receiving chute 7, and when vibration motor 1 vibrates, it avoids the impact on receiving chute 7. At the same time, the vibration of the vibrating motor causes the grating plate to swing within a certain range, so that the bulk material that cannot pass through the grate plate falls into the bulk chute 6 through the bulk raw material discharge port 5 along the inclined plane, and at the same time, the The vibrating motor is located on the side of the grating plate, which can avoid the collision when the grab is unloading.

In order to effectively separate bulk materials, the inclination angle of the grating plate can be determined through calculation, and then a better effect can be achieved by replacing the second connecting rod with different lengths.

Bulk materials fall into the bulk chute, and qualified materials fall into the receiving trough 7, which reduces the workload of manual picking, improves efficiency, and can be effectively connected with the next process.

This device can be used for the separation of impurities and large pieces of coal, ore and other materials in the raw material yard or blast furnace raw material system process before entering the tank, and the structure is simple, applicable, reliable in function, easy to repair and easy to cooperate with manual operation. Compared with traditional vibrating screening equipment, the process cost can be greatly reduced.
